I've been using provelone for quite some time and I've notice a great difference in flavors and oders from varying brands. I would blend it with differing ratios to subdue some of the stronger flavored provelones. But some are so strong that the attempt was futile.
Smoked hasn't shown to me, to automatically mean a strong flavored provelone. I've also noticed provelone has a tendence to develope stronger flavors when I store it in the refrigerator. I'm wondering if this would be true for unopened provelone logs.
Lately, I really enjoy the buttery combination of whole milk mozz and monterey jack, with the jack cheese at a smidge higher ratio than the mozz.
I thought I might also mention that shredding your own cheese will have better results than the pre-shredded. The pre-shredded is coated with an additive to prevent caking and aftects the the melting characteristics.
